Gambrel.

GAMBREL.

Applieationfiled February 6, 1918.

T 0 all whom it may concern:

.Be it known that I, FRED zen of the United States of America, and resident of Elkader, in the county of Clayton and State of Iowa, have invented certain new and useful Improvements in Gambrels, of which the following is a specification.

This invention relates to gambrels and particularly to novel means whereby the spreading action is augmented in proportion to the weight supported by the hooks and suspending means.

An object of this invention is to provide novel means whereby the supporting device is yieldably held so as to obviate undue vibration, jar and strain to the suspending mechanism when carcasses supported by the hooks are being treated, as for instance when they are being split.

A further object of this invention is to provide novel suspending means in which all of the yieldably held members are situated below a rigid frame, thus permitting the yieldable members to be suspended from the said frame, a construction which insures strength and durability, as well as efficiency.

With the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this specification, wherein like characters denote corresponding parts in the several views, and in which Figure 1 illustrates a view in elevation of the device; and

Fig. 2 illustrates a section on the line 22 of Fig. 1.

In these drawings 5 denotes a hanger bar with a loop 6 at its upper end for receiving a hook or other suspending means. The hanger bar has a slot 7 near its lower end and a cross bar 8 is slotted as at 9 to receive the hanger bar and the said hanger bar is attached to it by a pin 10. The hanger bar is also connected to the cross bar by braces 11 and 12 which diverge from the hanger bar and are connected to the cross bar near its ends, thus creating a relatively rigid framelike structure.

The cross bar has an aperture 13 near each end in which a curved shank 14 of a hook 15 is slidable, it being understood that Specification of Letters Patent.

slot 7 of the hanger bar and the pin constitutes a fulcrum on which the levers are pivotally mounted.

The levers are suspended by links 19 attached t0 the said levers by pivots 20 and the upper end of each link has a T-head 21 which lies in one of the recesses 22 constituting a seat for the said T-head, whereas the shank of the hanger extendsthrough the slot 9 of the cross bar. There is a plurality of recesses 22 and the link may be moved so as to be suspended from these to increase or diminish the inclination of the levers with respect to the horizontal. A spring 22 encircles each link and abuts a lever and the cross bar respectively so as to afi'ord a cushion action to the mechanism as it is operated.

From an inspection of the drawings and from the foregoing description, it will be apparent that when a carcass has been hung on the hooks, the weight of the carcass will tend to pull the outer end of each lever down and to raise the inner end of each lever, thus throwing or forcing the hooks outwardly according to the weight of the carcass as stated, and this is owing to the fact that the shanks of the hooks are held in the cross bar but owing to their curvature, there is a camining action which aids in forcing the hooks outwardly. The apertures 17 afiord an adjustment for shortening or lengthening the levers and the hangers are likewise adjustable to compensate for any adjustment which is given the levers.

I claim:

1. In a gambrel, a frame comprising a hanger bar and a cross bar suitably connected, the cross bar having an aperture near each end, levers, means for pivotally sup porting the levers intermediate their lengths, means for oscillatably holding the inner ends of the levers, and a hook pivotally connected to each lever, each of the said hooks having curved shanks slidable in an aperture of the cross bar.

2. In a gambrel, a hanger bar and a cross bar suitably connected, said cross bar having a slot intermediate its length and recesses on the upper edge of the slotted portion of the said cross bar, said cross bar having an aperture near each end, levers, means for pivotally supporting the levers from the cross bar, means for oscillatingly connecting the levers to the hanger bar, hooks pivot- 2115 connected to the levers, and curved shanks on the said levers guided in the apertures of the cross bar. 7 H

3. 111 a gambreha hanger bar and a slotted cross bar having recesses in its upper edge, links having T-heads fitted in the 1-6- cesses, and said links extending through the slot of the cross bar, levers pivoted to said links, hooks pivotally connected to the levers,means connected to the hooks and guided by the cross bar for controlling'the Copies of this natent may be obtained for action of the hooks, and means for guiding theinner ends or the levers.

l. In a gamhrel, a hanger bar and a'slotted cross bar having recesses 111 its upper edge, links having T-heads fitted in the recesses, said links extending throughthe slot of the cross bar, levers pivoted to thesaid each link between a lever and the cross bar,-
